JULIAN STRZYCZKOWSKI, OF NEW YORK, N. Y.

LAMINATED RAILROAD-TIE.

Specification of Letters Patent.

Patented Mar. 20, 1917..

Application filed October 31, 1916. Serial No. 128,559.

One of the objects of the invention is to' provide a tie having the characteristic features of the ordinary wooden tie but pos-' sessing greater durability.

Another object is to provide a tie in the construction of which there may be largely used scrap or refuse material, so that the first cost of the same is far less than of a solid railway tie.

These and other similar objects are attained by the novel construction and combination of parts hereafter described, and shown in the accompanying drawings, forming a part of the specification, and in which Figure 1 is a perspective view showing a preferred embodiment of the tie,

Fig. 2 is another perspective showing a modification in construction,

Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 1, and

Fig. 4 is a similar transverse sectional view taken on line 4.4 of Fig. 2.

In the construction of the ties, a plurality of leaves or layers 10, of wood, are used, having substantially parallel surfaces, the outer leaves 12, both at the top and bottom, extending entirely over the entire surface, while the inner layers may be of various lengths, the ends abutting one against the other as at 14k.

Inter-posed between these Wooden layers, are other layers of heavy tarred paper 15, the same being of equal extent or area to that of the upper and lower plate elements 12.

When the several layers have been placed in position, the entire tie is subjected to pressure suliicieut to solidify the whole into a complete mass, the plates being further maintained in position by means of the bolts 17, the heads 18 of which and nuts 19 are set within staggered openings, formed in the upper and lower elements respectively, in such a manner as to be level or flush with the surfaces, the nuts being tightened while the leaves are under compression so as to hold the same firmly together.

Another means of fastening the several layers is disclosed by the winding of a wire 20, as indicated in Figs. 2 and 4, the same being so applied as to be substantially level or flush, both at the tops and along the side edges of the tie.

By reason of the relatively thin plates of wood used, the tie possesses a greater degree of resiliency than if the structure were of integral construction, and on account of the tarred fabric interposed between the sevral layers, the wooden plates are subjected to antiseptic effects of the tar, rendering the tie less liable to the damage by moisture, whereby its life is increased over that of the ordinary solid tie made of wood only; furthermore, it is noticeable that as the interior plates may be of different lengths, that the tie may be constructed of stock which could not'otherwise be used for such purposes.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A tie comprised of a plurality of wooden plates and tarred fabric disposed between adjacent plates.

2. A tie comprised of a plurality of wooden plates, tarred fabric disposed between adjacent plates, and means for bolding said plates and fabrics in a rigid relation.

3. In a laminated tie, the combination with upper and lower elements covering the entire horizontal superficial area of the tie, of a plurality of wooden plates disposed between said elements, said plates being of uniform width, paper strips disposed between said layers, said paper strips being saturated with tar, and means for holding the said plates, said material being satuthe several elements comprising the tie in rated with tar, and means for holding the 1% a rigid, clamped condition. several plates tightly together.

4:. A laminated tie comprising a plurality Signed at New York, in the county of of Wooden plates, the outer plates having New York, and State of New York, this an unbrokensurface, the inner elements be- 29th day of September, 1916. ing of unequal lengths, flexible sheet ma- 7 terial disposed between adjacent layers of JULIAN STRZYCZKOl/VSKI.
